(2) Mixed or unsymmetrical ketone : The ketone in which the carbonyl carbon is ATTACHED to two different alkyl group is called a mixed or unsymmetrical ketone.
e.g., `{:(CH_(3)-overset(O)overset("||")C-C_(2)H_(5)""C_(3)H_(7)-overset(O)overset("||")C-C_(2)H_(5)),("Ethyl methyl ketoneEthyl n-propyl ketone"):}`
